Introduction

This is a hacked together test suite of a number benchmarks I use to run workloads on KVM/ARM and x86 platforms to evaluate the relative performance.

How to use

This is what you need:

• An ARM board that can run VMs (like an A15 of some sort)
• The ARM board must be running a KVM-enabled kernel
• The ARM board must be accessible by ssh using public key authentication to root@<board-ip> without providing a password
• The ARM board must have a script in root's home folder named run-ubuntu.sh, which runs a VM using either QEMU or kvmtool. Sample script for run-guest.sh is provided here - run-ubuntu.sh is just a wrapper that sets the name to ubuntu. The script will assume a file named ubuntu.img containing a file system image.
• The guest must use bridged networking and must also accept ssh connections using public key authentication just like the board itself: ssh root@<guest-ip>

Then, to run a test, you simply do: ./run-all.sh --help ...and follow the instructions

Experiments Logbook

To carry out the full test suite, we need:

• SMP numbers host/guest
• UP number host/guest
• ARM no vgic/timers guest SMP/UP
• LMBENCH ARM/x86
• Power Numbers

Laptop Notes

1. Boot host with "maxcpus=2 mem=1536M" on the kernel command line
2. Get non-graphics tty (ctrl+alt+f6)
3. shutdown not-needed services
   1. service lightdm stop
   2. service network-manager stop
   3. service avahi-daemon stop
4. for i in seq 0 1; do cpufreq-set -c $i -g performance; done;'
5. ./run-all.sh --host-only
6. TODO: LMBENCH
7. Boot host with "maxcpus=2 mem=2048M" on the kernel command line
8. Get non-graphics tty (ctrl+alt+f6)
9. shutdown not-needed services
   1. service lightdm stop
   2. service network-manager stop
   3. service avahi-daemon stop
10. sudo bash -c 'for i in seq 0 1; do cpufreq-set -c $i -g performance; done;'
11. ./run-all.sh --guest-only
